[0027] In the recrystallization operation of the raw material, the raw material is added to the heating cavity 101, and the raw material in the heating cavity 101 is heated by the heating wire in the heating barrel 1. When the temperature is lowered to the recrystallization temperature, the controller 203 controls the air pump 404 and the temperature control box 4 to be opened, and the temperature control box 4 adjusts the gas in the temperature control box 4 to the set temperature.

At this time, the gas in the temperature control box 4 is heated to the specified temperature. The gas is sprayed out through the air injection pipe 109 to heat and preserve the raw material, so that it can be kept at the specified temperature, and the heat energy stored in the heat storage sheet 302 in the energy storage cavity 301 can be reused, thereby effectively reducing the energy consumption of the temperature control box 4.
